BENNING MM 7-1



dimensions: length = 210 mm, tube length = 120 mm, tube diameter =

3 mm, V4A (P.no. 044121)

Note on replaceable parts:

- The BENNING MM 7-1 contains fuses for overload protection:

One fuse rated 11 A rapid-acting (1000 V) 20 kA, D = 10 mm, L = 38.1 mm

(P.no. 10016656) and one fuse rated 440 mA rapid-acting (1000 V), D =

10 mm, L = 34.9 mm (P.no. 10016655).

The BENNING MM 7-1 is powered by one 9-V block battery (IEC 6 LR 61 “micro”).

- The above mentioned safety cable (tested spare part) are approved in

accordance with CAT III 1000 V/ CAT IV 600 V and for a current up 10 A.

4. Description of unit

See fig. 1: Front panel

The display and operating elements shown in fig. 1 are as follows:



Digital display, for the measurement reading, bar graph and display for

overrange indication,



Polarity display,



Battery display,



RANGE key, switchover between automatic and manual measuring range,



VoltSensor key, for determining AC voltage to earth,



MIN/MAX key, storage of highest and lowest measurement value or peak

value,



Smart HOLD key,



Button (yellow), display illumination,



Function key (blue), for direct voltage/ current (DC) or alternating voltage/

current (AC), resistance or capacity measurement, continuity or diode test-

ing, frequency measurement, temperature measurement in °C or °F,



Rotating switch, for selecting measuring function.



Socket (positive

) for V, Ω, Hz, ,



COM socket, joint socket for measurement of current, voltage, resistance,

frequency, temperature, capacity, continuity and diode testing,



Socket (positive), for mA range, for currents up to 600 mA,



Socket (positive), for 10-A range, for currents up to 10 A,



Protective rubber holster

) The automatic polarity display for DC current and voltage refers to this.

5. General data

5.1 General data on multimeter

5.1.1 The digital display is designed as a 4 digit liquid-crystal indicator with 14 mm

digit height and decimal point. The highest value displayed is 6000.

5.1.2 The bar graph display consists of 62 segments.

5.1.3 The polarity indication



functions automatically. Only a polarity con-

trary to the socket definition is indicated, as “-”.

5.1.4 The range overload will be displayed with “OL” or “-OL” and sometimes

with an acoustic signal.

Attention: no display or warning by complete overload.

5.1.5 The “RANGE” key



can be used to change over to the manual meas-

uring ranges and to hide “AUTO” on the display at the same time. By

pressing the key for approx. 2 seconds, the automatic range selection is

activated (“AUTO” on the display).

5.1.6 Volt sensor key



: The voltage indicator function is intended for local-

izing AC voltages to earth (see 8.9).

5.1.7 The “MIN/MAX” key  function records and stores the highest and low-

est measurements automatically. By pressing the button several times,

the following values are shown: Display “MAX/MIN” shows the current

measurement value, “MAX” shows the highest value stored and “MIN”

the lowest value stored. The “HOLD” key serves to interrupt the “MIN/

MAX” function. When the key is pressed for 2 sec. the unit switches

back to normal mode. Press the “MIN/MAX” key



for 2 seconds to

switch over to the “PEAK” function (peak value storage). The “PEAK”

function detects and stores the positive and negative peak/ crest

value (> 1 ms) in the mV, V AC/ DC and mA, A AC/ DC function. The

automatic range selection is deactivated in the MIN/ MAX and PEAK

function.

5.1.8 “Smart HOLD” - storage of measurement reading: When the “Smart

HOLD” key  is pressed, the measurement reading is stored in the

memory. The symbol “HOLD” appears in the display at the same time.

If the measured value increases by 50 digit above the saved value the

change in measured value is shown by a blinking display and by a

signal tone. (changes of measured values between AC and DC voltage/

current will not be recognized).
